Electric Motor Controls - Danfoss
Electronic motor control is vital for modern pump systems, enhancing efficiency and reliability by managing motor speed, torque, and direction. Utilizing variable frequency drives (VFDs) and programmable logic cont...
Adjustable frequency drives (AFDs/VFDs) control pump motor speed to match demand. Slowing a pump even slightly can cut energy use dramatically, and drives also provide soft starts and process control.
Benefits for Pumps
- Energy savings – match pump speed to system demand
- Constant pressure control – booster and water systems
- Soft start and stop – reduce water hammer
- Pump protection – dry-run and overload detection
- Multi-pump control – alternate and stage pumps
Choosing a Drive
Size the drive to motor current and voltage. Pump-specific drives include PID control and pump features. Consider enclosures, filters and bypass options.
Centro supplies AFDs for pump control applications.

Pump soft starters gradually ramp motor voltage to cut starting current, torque spikes and water hammer. They're a cost-effective way to protect pumps, piping and electrical systems when speed control isn't needed.
Features
- Pump control algorithms – smooth start and stop curves
- Built-in bypass – reduce heat during running
- Motor protection – overload and phase loss
- Compact design – save panel space
Choosing a Soft Starter
Size by motor current and voltage, and select pump-specific stop control to cut water hammer. Consider ambient temperature and enclosure.
Centro supplies soft starters for pump applications.
